Digital BW, The Print

No, this wasn't a lighting thing, or a chamelion thing, or a color
perception or personal thing. These were pre-filled Epson 9000
cartridges from MIS, and on Museo at least, the images looked decidedly
green in *any* light -- low voltage halogen, daylight, ott-lite. Each
person who saw the prints said something like "Yuk, those look really
green!"

I cannot say with certainty what caused this. I assume it was some kind
of contamination in the ink, or a bad batch, or whatever. I called MIS
and explained the problem. They said "send 'em back," no hassle or
push-back whatsoever, and credited my account.

By the way, the variable-tone option Bernd notes can't remove a green
cast. In terms of L*a*b* coordinates, the variable tone gives you (more
or less) +/- b* control, and the green cast is a -a* problem.

I had been thinking for some time about blending my own ink set, so
after this happened, I went ahead and did it. Initial results are *very*
encouraging; I'll post a more complete report when I have more complete
results.
